CARBURETING-LAMP.

SPECIFICATION forming part of Letters Patent No. 430,778, dated June 24, 1890.

Application filed May 19, 1886.

To all whom it may concern.-

Be it known that we, WILLIAM SMITH lion- RY, a citizen of Great Britain, residing at 52 West Fourteenth street, New York city, State of New York, and ARTHUR KITSON, a citizen of Great Britain, residing at 1832 Mount Vernon street, Philadelphia, State of Pennsylvania, have conjointly and together invented certain new and useful improve- IO ments in carbureting-lamps for preheating illuminating-gas and heating air in which gas is consumed for the purpose of increasing the illuminatingpower of gas; and We do hereby declare that the following is a full, clear, I5 and exact description of our invention.

Our invention has reference to gas chandeliers and lamps; and it consists in certain improvements, all of which are fully set forth in the following specification, and shown in the accompanying drawing, which forms part thereof.

In the drawing is shown a sectional elevation of a chandelier or gas-lamp-embodying our invention.

A represents the gas-supply pipe, and is arranged vertically, adapted to be connected with the gasmain at the top and communicating with the burners at the bottom.

Bis a metallic ribbon twisted into spiral o shape and inserted into the vertical supplytube, so as to form two circuitous or spiral gas-passages through the same, whereby the gas in descending through the supply-pipe is divided, then caused to pass down with the 3 5 spiral motion, and finally reunites before pass ing to the burners O, which are preferably arranged equidistant about the lower portion of said supply-pipe.

D is a casing surrounding the supply-pipe and forming the annular compartment J,

making in some respects a dome of small diameter, but of great depth. The upper portion of this compartment J is preferably closed, as at I, but, if desired, may have a 5 very small outlet H, so as to allow a slow change of the contents of the compartment J. The lower portion of the casing D is extended into a bell G, which is arranged a Serial No. 202,598. (No model.)

short distance above the burner-flames, and is adapted to catch and arrest the products of combustion, causing them to pass into the annular chamber J and remain in direct contact with the supply-tube A, for the purpose of heating the gas before being admitted to the burner. Bythis construction the supplytube is fully protected against transverse cooling-currents, and is in direct contact with a practically stationary volume of highlyheated products.

E represents a carbureting or enriching receptacle, andis adapted to contain suitable hydrocarbon, either in the liquid or solid state, capable of being readily volatilized, and is in communication with the lower extremity of the supply-tube A and burner O by a neck or tubular connection F, provided with a coupling K, which screws into the supply-pipe A, and is removable therefrom for refilling. The ribbon B preferably extends down somewhat in the receptacle E, the object being to cause the incoming gas, after being highly heated, to enter the receptacle E with the spiral motion, whereby it is caused to positively pass over the contents therein, thereby taking up enough of the enriching material to give a most brilliant light when burned at the burners O. By this construction of chandeliers the gas is thoroughly and uniformly heated, and no excessive heating or undue cooling can possibly take place, and the gas is maintained at auniform composition and temperature, and therefore emits a steady light.

The chandelier admits of being readily cleaned, as the spiral ribbon may easily be removed. The construction is extremely simple and novel, is easily repaired, and not liable to be put out of working order.

I/Ve are aware of the Victoria patent, No. 2,739, of 1879, in which is shown a gas-inlet made of tubing, twisted into a spiral with one tubular passage-way, such tube connecting with the gas-burners, and being surrounded by a case made open at the top, and do not claim any such constructions.

In this application the matters claimed are specifically set out in the claims, and all other constructions not here claimed form subjectmatter of our application filed October 13, 1886, Serial No. 216,127, and also our application filed November 24:, 1886, serially numbered 219,765.

' Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a chandelier, the combination of the burners with a centrally-located vertical and tubular supply-pipe, anda ribbon fitting diametrically within said supplypipe, the burners located in proximity to said supply-pipe and spirally twisted to cause the gas to be divided and assume a spiral movement to bring all portions thereof in contact with the sides of the tube, substantially as and for the purpose specified.

2. In a chandelier, the combination of the burners with a centrally-located vertical and tubular supply-pipe, a spiral ribbon placed within said supply-pipe to cause the gas to be divided and assume a spiral movement to bring all portions thereof in contact with the sides of the tube, a surrounding case inclosing the said supply-pipe arranged above the burners, and substantially closed at its upper end for holding the heated products of combustion from the burners in contact with the gas-supply pipe, and a vessel containing a highly-volatile hydrocarbon in communica tion with both burners and supply-tube and located below the burners.
